From Brian Williams's July 13 Daily Nightly blog entry:
"Full disclosure: I had agreed to participate in the all-day msnbc.com live blog [about the Senate confirmation hearings for Sonia Sotomayor], but found I didn't have a thing to say that would add to the conversation...so I held off."
As a self-professed "Supreme Court buff", I guess Brian was attempting to imitate one of the Justices by recusing himself. So what's Brian's excuse for all the other times when he doesn't recuse himself from commenting on a wide variety of subjects despite having nothing to add to those conversations? Brian should stick to reading from his teleprompter and leave the expert commentary to the experts.
